Some buildings have creative slanting pillars, and many others have escalators.

But these features pose a danger to visually impaired people, unless precautions are taken. This is because those who are visually disabled typically use a cane to detect obstructions on the ground, but not anything above the chest.

I hope building owners can be mindful of these problems, and place items such as potted plants at "danger spots".

The cane will be able to pick up such items on the ground and prevent people who are visually disabled from walking into slanting pillars or the protruding backs of escalators.
